Flag that indicates whether the Provider or Consumer creates an Endpoint per
arrived Connection Request. The value of \fBDAT_PSP_PROVIDER\fR indicates that
the Consumer wants to get an Endpoint from the Provider; a value of
\fBDAT_PSP_CONSUMER\fR means the Consumer does not want the Provider to provide
an Endpoint for each arrived Connection Request.

.SH DESCRIPTION
.sp
.LP
The \fBdat_psp_create_any()\fR function creates a persistent Public Service
Point that can receive multiple requests for connection and generate multiple
Connection Request instances that are delivered through the specified Event
Dispatcher in Notification events.
.sp
.LP
The \fBdat_psp_create_any()\fR function allocates an unused Connection
Qualifier, creates a Public Service point for it, and returns both the
allocated Connection Qualifier and the created Public Service Point to the
Consumer.
.sp
.LP
The allocated Connection Qualifier should be chosen from "nonprivileged" ports
that are not currently used or reserved by any user or kernel Consumer or host
ULP of the IA. The format of allocated Connection Qualifier returned is
specific to IA transport type.
.sp
.LP
The \fBdat_psp_create_any()\fR function is blocking. When the Public Service
Point is created, \fBDAT_SUCCESS\fR is returned, \fIpsp_handle\fR contains a
handle to an opaque Public Service Point Object, and \fIconn_qual\fR contains
the allocated Connection Qualifier. When return is not \fBDAT_SUCCESS\fR,
\fIpsp_handle\fR and \fIconn_qual\fR return values are undefined.
.sp
.LP
There is no explicit backlog for a Public Service Point. Instead, Consumers can
control the size of backlog through the queue size of the associated Event
Dispatcher.
.sp
.LP
The \fIpsp_flags\fR parameter allows Consumers to request that the Provider
create an implicit Endpoint for each incoming Connection Request, or request
that the Provider should not create one per Connection Request. If the Provider
cannot satisfy the request, the operation shall fail and
\fBDAT_MODEL_NOT_SUPPORTED\fR is returned.
.sp
.LP
All Endpoints created by the Provider have \fBDAT_HANDLE_NULL\fR  for the
Protection Zone and all Event Dispatchers. The Provider sets up Endpoint
attributes to match the Active side connection request. The Consumer can change
Endpoint parameters. Consumers should change Endpoint parameters, especially PZ
and EVD, and are advised to change parameters for local accesses prior to the
connection request acceptance with the Endpoint.
